对来自威斯康星州多个废水处理设施的样本进行了筛查，以确定是否存在21种抗生素化合物。这些设施涵盖了一系列的社区规模服务（平均日流量从0.0212到2360万加仑/天），二级处理过程，地理位置横跨国家，他们排放处理后的污水到地表水和地下沃茨（地下水后，土壤通道）。共检测到6种抗生素化合物（每个部位1 - 5种化合物），包括两种磺胺类药物（磺胺二甲嘧啶、磺胺甲恶唑）、一种四环素（四环素）、氟喹诺酮（环丙沙星）、大环内酯（红霉素-H2O）和甲氧苄啶。抗生素检出率依次为四环素和甲氧苄啶（80%）>磺胺甲恶唑（70%）>红霉素-水（45%）>环丙沙星（40%）>磺胺二甲嘧啶（10%）。然而，可溶性浓度在十亿分之一（ppb）范围内（
Samples from several wastewater treatment facilities in Wisconsin were screened for the presence of 21 antibiotic compounds. These facilities spanned a range of community size served (average daily flow from 0.0212 to 23.6 million gallons/day), secondary treatment processes, geographic locations across the state, and they discharged the treated effluents to both surface and ground waters (for ground water after a soil passage). A total of six antibiotic compounds were detected (1-5 compounds per site), including two sulfonamides (sulfamethazine, sulfamethoxazole), one tetracycline (tetracycline), fluoroquinolone (ciprofloxacin), macrolide (erythromycin-H2O) and trimethoprim. The frequency of detection of antibiotics was in the following order: tetracycline and trimethoprim (80%)> sulfamethoxazole (70%)> erythromycin-H2O (45%)> ciprofloxacin (40%) > sulfamethazine (10%). However, the soluble concentrations were in the parts-per-billion (ppb) range (
